Came here on a past trip to Taiwan, and here's my Water Drop Teahouse review for happycow.
Jiaosi (Jiaoxi) is a hot springs destination with strings of hotels but only a few vegetarian food options. This place was very nice.
The menu is concise but offers enough options that you could come back a few times. The space is well-kept and nice enough for fine dining, but it's actually meant for causal dining. The food prices are fair. A few of us ordered some food to share. The lotus flower hot pot is very tasty. The sesame sauce noodle is excellent. I didn't like the green fried rice because it had a strange flavor to it. Tasty fried spring rolls.
I recommend it when you're in the area.Pros: nice space, lovely front garden, tasty food
